Dural Venous Channels: Hidden in Plain Sight-Reassessment of an Under-Recognized Entity.

ABSTRACT:

Background and purpose

Tentorial sinus venous channels within the tentorium cerebelli connecting various cerebellar and supratentorial veins, as well as the basal vein, to adjacent venous sinuses are a well-recognized entity. Also well-known are "dural lakes" at the vertex. However, the presence of similar channels in the supratentorial dura, serving as recipients of the Labbe, superficial temporal, and lateral and medial parieto-occipital veins, among others, appears to be underappreciated. Also under-recognized is the possible role of these channels in the angioarchitecture of certain high-grade dural fistulas.

Materials and methods

A retrospective review of 100 consecutive angiographic studies was performed following identification of index cases to gather data on the ang
